ELECTRIC HEADLIGHT.

Application filed October 14, 1921.

and exact description, such as will enable others skilled in the art towhich it'appertains to make and. use the same. a

This invention relates to electric head-.

lights, and has for its main object to provide a serviceable andinexpensive headlight of such construction that the lens, reflector andlamp can be removed quickly and without the necessity of first removinga number of small screws orother retaining devices that are dificult tohandle or manipulate.

Another object is to provide an'electric headlight which is equippedwith a divided casing that is constructed in such a manner that when itis open or the sections of same separated, the lens, reflector and lamwill be exposed to view and can be easi y removed. Other objects anddesirable features of our invention-will be hereinafter pointed out. Tothis end we have devised headlight that is rovided with a casingcomposed of a plura lty of sections separated or divided by joints whichextend longitudinally of the casing and provided on their inner sideswith ribs, coves or the like that hold the lens and t e reflector in aposition at right angles to the lon itudinal axis of'the casing.- Gneelement 0 the easing is provided with a support for the socket thatholds the incandescent'lamp oi the headlight, and a movable oradjustable element co-operates with said sup ort to re- .tainsaid socketin operative position.

accordance withour invention, showing the two sections of the casing searated.

Referring 'to the drawin s which illus; trate the preferred foim 0 ourinvention,

A and A designate two semi-cylindrical shaped members that cooperatewith each other to form a cylindrical casing that houses anelectricincandenscent lamp B, a lens C and a reflector D; The joints between themembers A- and A, are located preterably at the horizontal center of thecasing haljf of the casing and the member A the top half. Said memberscan be connected together in any suitable way thatwillpermit them to beseparated easily so as to expose the lens, lamp and'reflector, but wepjrsfer to connect said'members together by ges 1 so as to enable thetop half .or section A of the casing to be swung into the pos1t1on shown111 Figure 1 when it is desired to inspect or remove the elements of.the headlight that are arranged inside of the casing. Normally, is heldclampedtifghtly member A by means of a fastening device whlch mayconsist of a screw: 2 pivotally connected by a pintle pin 3 to a pair oflaterallyprojecting lugs 4 on the bottom member A and provided with awing nut 5 that is adapted tb bear the topfmember A against the bottomlugs don the top section A of the casing, said screw being adapted to beswung on its pivot Into and out of engagement with the lugs i on the topsection of the casing,

1e lens and the reflector are loosely mounted in transversely-disposedgrooves 6 and 7, respectively, in the bottom section A of the casing,and the top section is pro vided with co-operating grooves 6 and 7 thatreceive said lens and reflector when the top section of the casing ismoved into its closed position. The lamp B is mounted in a lamp socket 8that is seated in a semi-circular-shaped supportt that extendstransversel of the bottom member A oi the casing a j acent the rear endof same, said lamp socket being retained in position preferably bya'clam'ping member 10 pivotally connectedby a hin e l1 tothe transversel-disposed lamp soc et support and provi ed at lts free, end with anelongated slot 12 for an "upwardly-projecting, screwreceivin thread Stud13 on-which a wing nut 14 is adapted to be mounted after the clamp 10against a bifurcated I v aw or pair of laterallyprojecting an electricwill form the lower has been swung downwardly into engagement with thesocket,'as shown in full lines in Figure 3. When it is desired to adjustor i be formed from any suitable material, but

when the headlight is designed for use on an electric storage batterymine locomotive, we prefer to cast said members and provide the meeting.edges of same with laterally-projecting flanges 15, so that the topmember of the casing will have a. firm bearing on the bottom member, thelugs and l and the ribs that form the grooves which receive the lens andthe'reflector being integrally connected to the members of which theyform a part;

In the form of our invention herein illustrated the bottom member A ofthe casing is provided with integral, laterally-projecting lugs 16through which fastening-devices are passed to connect the headlight tothe structure on which it is mounted. The lens C is preferably setinwardly some distance from the extreme front end of the casing, and thetop member A of the casing is provided with a forwardly-projecting hood17 that tends to protect the lens. Ventilating openings 18 are formed in-the top of the casing and the bottom part of the casing is pro videdwith an air inlet opening '19 so as to cause air to circulate throughthe casing. If desired, the top member A may be provided on its outerside with integral hoods or shields 20 for preventing dirt from blowinginto the casing through the ventilating openings 18 therein.

With a headli ht of the construction above described it is a very simplematter to inspect or remove the lens, reflector and lamp, owing to thefact that the casing is divided longitudinally into a number oi sectionsthat can be easily separated, so as to expose the lens, reflector andlamp, the lens and reflector being loosely mounted in one section oi thecasing and the lamp socket being retained in position by a hinged clampsecured by a wing nut. While our improved headlight is not limited touse with an electric storage battery mine locomotive, it is particularlyadapted for such use, on account of its rugged construction and the easewith which the lens, lamp and reflector can be inspected or removed, itbeing unnecessary to remove 'or manipulate a number of.

small screws or other retaining devices to gain access to the interiorof the casing or to remove the lens and reflector. In addition to thedesirable features above pointed out, our improved headlight isinexpensive "to manufacture, as the casing is so designed thatco-operating integral portions on the,

sections of same hold and clamp the lens and reflector in operativeposition.

Lesopoa Having thus described our invention, what we claim as new anddesire to secure by Letters Patent is:
